Fatty liver has become a recognized liver disease worldwide and is considered a common cause of unexplained cirrhosis, and more than 50% of the fatty liver population is a backup to diabetes. Fatty liver is a precursor to many diseases. 1. Fatty liver predisposes to hyperlipidemia. The liver is the largest metabolic organ in the body, and fatty liver causes abnormal liver fat metabolism, which is manifested by elevated triglycerides or cholesterol in the blood. Fatty liver is often accompanied by abnormal blood lipids, because high blood lipids increase blood viscosity, blood runs slowly, lipid deposition in the vascular wall, resulting in poor vascular elasticity, causing hypertension; too much lipid deposition in the vascular wall, easy to cause hardening of the vascular wall, occurring in the arterial vessels, is atherosclerosis; due to the blockage of blood lipids, the vascular lumen becomes increasingly narrow, easy to lead to insufficient blood supply to the heart muscle, insufficient oxygen supply to the brain This can cause heart disease, stroke and other serious consequences. 2, fatty liver easily lead to cirrhosis According to information reports, although fatty liver is a benign lesion, but about 1/4 of patients can occur cirrhosis. Fatty liver causes impaired fat metabolism in the liver, excessive fat accumulation in liver cells, causing swelling and rupture of liver cells, fat overflow in liver cells, causing fat infiltration of liver cells; broken liver cells cannot be repaired in time, causing inflammation of liver cells, which in turn leads to steatohepatitis. At this time, elevated transaminases and transpeptidases are clinically detected. After the rupture of hepatocytes, excessive dead tissues cannot be cleared in time and gather in the liver, at which time the body repairs the damaged hepatocytes, resulting in insufficient raw materials for hepatocyte synthesis, and the body can only use relatively more raw materials in the body to repair, thus forming liver fibrosis. When liver fibrosis continues to develop and the liver hardens, cirrhosis is formed. Cirrhosis often occurs as ascites, gastrointestinal hemorrhage or liver failure. 3.Fatty liver often causes type II diabetes, kidney stones, gout, cholecystitis and many other diseases. Fatty liver can lead to impaired glucose metabolism and type II diabetes; fatty liver makes protein catabolism abnormal, leading to high uric acid, and prolonged abnormal uric acid excretion will form crystals in the kidney, leading to kidney stones and gout. Fatty liver affects the secretion of bile and the drainage of bile by the liver, and bile acid, the main component of bile, is easily precipitated in bile, forming gallstones; bile acid is more irritating to the gallbladder, forming cholecystitis. It can be seen that a variety of diseases occur from the abnormal liver function caused by fatty liver.
